OfficeIMO.Visio

Why OfficeIMO.Visio?

OfficeIMO.Visio lets you generate and modify .vsdx diagrams from pure .NET code. Build network topologies, org charts, flowcharts, timelines, swimlanes, dependency graphs, and architecture diagrams without requiring Visio on the machine. Builder APIs keep common diagrams concise, while lower-level pages, shapes, connectors, masters, and stencil catalogs remain available when you need precision.

Features

Create, load & save .vsdx files -- full round-trip support for the Visio Open XML format
Diagram builders -- create flowcharts, architecture diagrams, networks, dependencies, swimlanes, org charts, timelines, sequences, and generic graphs
Stencils and catalogs -- use generated catalogs, installed Visio stencils, or external .vssx / .vstx packs
Connectors with metadata -- connect shapes with labels, hyperlinks, Shape Data, waypoints, and routing hints
Fluent and low-level APIs -- chain common diagrams or edit individual pages, shapes, connectors, and masters
Multiple measurement units -- work in inches, millimeters, centimeters, or points
Connection points -- define and target specific connection points on shapes for precise routing

Diagram types you can automate

Diagram type	Typical source data	Outcome
Infrastructure topology	Inventory exports, deployment metadata, cloud resources	Repeatable architecture diagrams that stay in sync with real systems
Process and approval flows	Workflow definitions, queue stages, or policy steps	Clear step-by-step diagrams for operations and compliance teams
Org and service maps	HR systems, ownership registries, service catalogs	Diagrams that show teams, responsibilities, and platform boundaries
Release and runbook visuals	CI pipelines, deployment targets, or support procedures	Supporting diagrams that travel with Word reports and PowerPoint decks

Where Visio fits in the suite

Pair it with	Use the combination for
OfficeIMO.Word	Architecture reports, runbooks, and handoff documents that include generated diagrams.
OfficeIMO.PowerPoint	Stakeholder decks where the same topology or workflow data becomes presentation material.
OfficeIMO.CSV	Inventory-driven diagrams where nodes, owners, environments, or dependencies start in flat files.
OfficeIMO.Reader	Indexing generated diagram metadata alongside related documents for search or review workflows.

Quick start

using OfficeIMO.Visio;
using OfficeIMO.Visio.Diagrams;

VisioDocument.Create("Architecture.vsdx")
    .ArchitectureDiagram("System Overview", diagram => diagram
        .Title()
        .Legend()
        .Theme(VisioStyleTheme.Technical())
        .Region("vnet", "Virtual Network", 1, 0, 3, 2)
        .Actor("users", "Users", 0, 1)
        .Gateway("gateway", "Gateway", 1, 1)
        .Service("api", "API", 2, 1)
        .Database("database", "Database", 3, 1)
        .DataFlow("users", "gateway", "HTTPS")
        .ControlFlow("gateway", "api", "route")
        .DataFlow("api", "database", "SQL"))
    .Save();

Repeatable modeling flow

Start from the system, process, or ownership data you already have instead of hand-placing every shape.
Map each entity to a stable shape type, label, and color so regenerated diagrams stay easy to compare.
Use connectors to represent traffic, dependency, or approval flow, then reserve shape text for the labels people need to scan quickly.
Generate the .vsdx file as part of a report build, architecture export, or operational handoff package.
Pair the diagram with OfficeIMO.Word or OfficeIMO.PowerPoint when the same workflow also needs narrative or presentation output.
